Any active plugins?
Changes to your templates?
Updates to your server that you’re aware of?
No plugins, no changes in the template, and no listed updates on my server.
Things happen for a reason. If it wasn’t doing so before, try and identify what has changed since and run through them one by one.
Really nothing as far as coding. but there is now a huge amount of articles on the blog. But that is all I can think of as far as new.
It also does not do it all the time. strange.
It was because ping back was hard wired on in my edits.php and advanced edits.php. I edited them to allow me to turn them of and now everything is fine. I have no use for pingback.
I think I may not have the newest version since it was already on my server when I purchased the account. But I am not going to upload the possibly newer files, because I have no problem with pingbacks or trackbacks.
